Did you build the building from scratch or is it a portable building you placed on top of the deck?
it is a angle iron shipping crate covered with sheet metal that my brother gave me. he works tool and die and they ordered a new cnc machine that came in this shipping container. i only used the four walls, pre-assembled it in my garage.painted itand put in the windows. then took it apart, hauled it out to the deck and assembled it. pre-fab the roof trusses also. so that it was ready to assemble in a weekend and under roof. i will submit the pics as soon as i can find them.
